Abstract
Fins are each formed with a flat shape in a height direction, which is orthogonal to a flow direction of coolant in a coolant passage, and a plurality of the fins are provided intermittently along virtual waveforms extending in the flow direction and making a plurality of rows in a width direction that is orthogonal to the height direction and to the flow direction. An upstream portion of a first fin provided in a first row overlaps with the position in the flow direction f of a downstream portion of a second fin provided in a second row adjacent to the first row. Furthermore, the downstream portion of the first fin overlaps with a position in the flow direction of an upstream portion of a third fin provided in the second row.
Claims5
A cooling apparatus comprising a plurality of fins within a coolant passage near a heat source body,
- wherein the plurality of fins each have a flat shape in a height direction orthogonal to a flow direction of coolant in the coolant passage, and are provided intermittently along virtual waveforms that extend in the flow direction and that make a plurality of rows in a width direction orthogonal to the flow direction and to the height direction, and
- with a fin provided in a first row being a first fin and two fins lined up in the flow direction and provided in a second row adjacent to the first row being a second fin and a third fin, an upstream portion including an upstream end of the first fin overlaps with a position in the flow direction of a downstream portion including a downstream end of the second fin, and a downstream portion including a downstream end of the first fin overlaps with a position in the flow direction of an upstream portion including an upstream end of the third fin.
